High-efficiency energy storage and primary power cells customized for industrial, residential, and commercial applications in North America.
Howell Energy Co., Ltd is a high-tech enterprise group dedicated to green and sustainable energy. With over 20 years of focus in the battery industry, we have become one of the premier Lithium Battery Export Enterprises, serving key commercial and industrial partners across the United States. Through continuous R&D innovation and scientific management, we are committed to delivering professional, efficient clean energy solutions to our global customers.
We specialize in the research, development, production, and sales of a wide range of battery products, including LiFePO4 batteries, Li-ion batteries, Li-polymer batteries, lithium primary batteries, NiMH & NiCd batteries, and integrated energy storage systems (ESS). We also offer full custom battery services—from battery design, development, and cell selection to advanced BMS integration—providing one-stop energy solutions tailored to our customers' specific needs.
Understanding the commercial dynamics, grid requirements, and strict regulatory standards driving the North American battery market.
The United States is currently undergoing a massive energy transition, with lithium batteries serving as the cornerstone of this shift. From state-level mandates in California and Texas to federal incentives like the Inflation Reduction Act (IRA), the demand for high-density, reliable energy storage has reached unprecedented heights. Commercial facilities, manufacturing plants, and data centers across the US are actively deploying large-scale Lithium Iron Phosphate (LiFePO4) systems to mitigate peak-demand charges, ensure uninterruptible power supplies (UPS), and achieve corporate sustainability goals.
Furthermore, the rapid expansion of the internet of things (IoT) and smart infrastructure in North America has created a parallel demand for highly reliable lithium primary cells. Municipalities are upgrading water, gas, and electricity grids with smart meters that require a stable 10-to-15-year operational lifespan, which can only be achieved through premium-grade primary chemistries like Li-SOCl2 (Lithium Thionyl Chloride). Howell Energy meets this demanding requirement by exporting UL-certified ER26500 and ER14505M cells built to withstand extreme US climates.
Safety and compliance are the absolute priorities for the US battery market. Any lithium battery system imported into the United States must adhere to rigorous testing standards, including UL 1642 for cells, UL 1973 for battery packs in stationary applications, and UN 38.3 for safe transportation. Additionally, developers of utility-scale energy storage systems (BESS) look for compliance with UL 9540 and UL 9540A thermal runaway testing. Exporters who cannot provide these verifiable certifications are locked out of the US supply chain.
Chemically, the industry is witnessing a clear shift toward LiFePO4 (Lithium Iron Phosphate) for stationary and deep-cycle applications. Compared to traditional cobalt-based chemistries, LiFePO4 offers superior thermal stability, a longer cycle life (often exceeding 5,000 to 6,000 cycles at 80% DoD), and is free from conflict materials. This makes it the preferred choice for residential solar storage walls and commercial backup systems. Concurrently, the primary lithium market continues to rely heavily on Li-SOCl2 for its exceptionally low self-discharge rate and wide operating temperature range.
Partnering with an established exporter like Howell Energy allows US distributors to navigate the complex regulatory and logistical landscape of battery importation. By offering fully compliant products with complete UL, CE, CB, and RoHS certification paths, we ensure that our partners can integrate our battery packs directly into US commercial projects, smart grid systems, and consumer electronics without regulatory delays. Our robust supply chain and factory-direct pricing provide a crucial competitive edge in the rapidly expanding American market.
How our battery solutions address specific regional, industrial, and infrastructure requirements across the United States.
Across the United States, utility companies are modernizing their infrastructure to create smart grids. This requires millions of gas, water, and electricity meters to operate autonomously in harsh outdoor environments for over a decade. Our primary lithium cells, such as the ER26500 and ER14505M, are engineered specifically for these low-drain, long-term applications. They feature an extremely low self-discharge rate (less than 1% per year at room temperature) and a rugged hermetic seal, ensuring uninterrupted data transmission and eliminating costly battery replacement truck rolls for US utility providers.
We combine decades of technical expertise with a deep understanding of US market compliance and quality expectations.
All exported battery packs and cells strictly comply with UL, CE, CB, UN38.3, KC, BIS, and RoHS directives, ensuring smooth customs clearance and local compliance in the US.
We provide full custom battery services, from mechanical design and cell matching to custom BMS development, tailored to the exact specifications of your US application.
With over two decades of dedicated R&D in battery technology, we deliver mature, high-performance energy storage products designed for durability and safety.
Deep dive into technological advancements, recycling mandates, and grid integration strategies.
In the United States, safety is paramount, particularly for indoor residential and commercial installations. This has driven a major transition away from Nickel Manganese Cobalt (NMC) chemistries toward Lithium Iron Phosphate (LiFePO4). LiFePO4 possesses an inherently stable chemical structure that prevents thermal runaway even under mechanical damage or electrical abuse. This is a critical factor for complying with strict local building and fire codes (such as NFPA 855 standards for the Installation of Stationary Energy Storage Systems) enforced across various US states.
Our 48V Power Wall systems and high-capacity 48V 308Ah battery packs leverage premium LiFePO4 cells to offer US customers a safe, long-lasting alternative. With advanced integrated Battery Management Systems (BMS), these packs communicate seamlessly with leading inverter brands popular in the US market, ensuring optimal charge rates, cell balancing, and comprehensive protection against over-voltage, under-voltage, and thermal anomalies.
The US electrical grid is facing dual challenges: an aging infrastructure and an increase in extreme weather events. Consequently, businesses and homeowners are actively investing in decentralized energy storage systems (ESS). By combining solar PV arrays with high-capacity battery packs, users can create microgrids capable of operating independently during utility grid outages. This is especially prevalent in states like California, Texas, and Florida, where grid instability is a growing concern.
From a commercial perspective, these battery systems enable "peak shaving." By charging during off-peak hours when electricity rates are low and discharging during peak demand periods, US businesses can significantly lower their monthly utility bills. Howell Energy's high-capacity battery modules are designed to scale, allowing commercial integrators to build custom storage arrays that meet specific load profiles and deliver rapid return on investment (ROI).
